Q:I need to replace some older dewalt hammers that I cannot find made anymore.
A:Yes, the D25553K is a replacement for model D25550 spline rotary hammer
Q:I am interested to know what size concrete coring bits this rotary hammer can handle. We do a lot of drilling for drain pipes in concrete walls and need to use coring bits up to 4 3/4" for 4" PVC pipe. I also have drill bits from a Hitachi rotary hammer that are spline drive and would like to know if these are compatible with this rotary hammer. Thanks, Jim
A:This drill has a maximum drilling capacity of 1-9/16. For a drill that uses a core bit, we recommend using a larger drill.
